` RAILWAY HOPPER CAR l l v Filed June 5, 1929 @duidt/M0155' n PatentedApr. 29, 1930 UNITED STATES WILLIAM E. WINE, OF TOLEDO, OHIO I RAILWAYHOPPER CAR Application led June 3, 1929. Serial No. 368,081.

My invention relates to railway hopper cars and more particularly to thehopper construction and associated door frame.

A principal object of the invention is to provide a strong and rigiddoor frame which may` be economically manufactured and which is soformed that it may be associated with the hopper sheets in a manner toproduce a hopper having a'large capacity. a

A primary feature of the invention consists in providing the door framewith a plurality of flanges adapted to be respectively secured to theinner and outer side sheets and inclined floor sheets of a hopper, theflange of the frame and the portion of the inner side sheet, which aresecured together being disposed at an angle to the general plane of thesaid inner sheet.

Another feature of the invention resides in forming a door frame forahopper car with a plurality of flanges adapted to be respectively'secured to each of the sheets defining the hopper, the portion of theinner` side sheet of the hopper to which the door frame is securedbeingbent inwardly.

Other and more specific features of the invention residing inadvantageous forms and combinations and relations of parts willhereinafter appear and be pointed out in the claims.

In the drawings illustrating a preferred embodiment of the invention:Figure 1 is a fragmentary transverse sectional view of a railway hoppercar embodying the invention.

Figure 2 is a sectional view taken' on -line 22, Figure 1. v

Figure 3 is an enlarged fragmentary sectional view taken on line 3 3,Figure 1.

. Figure 4 is an enlarged sectional view taken on line 4 4, Figure 1,illustrating only the door frame and outerside sheet of the hopper.

Referring more particularly to the drawings 1 indicates one of thecenter sills of the car and 2 one of the side sills thereof. The hopperof the car, generally designated by the reference numeral 3, is formedby inner and outer side sheets 4 and 5, respectively, and a floor orslope sheet 6. The outer side sheet 5 inclines downwardly and inwardlyfrom the side sill 1 and is offset adjacent its upper edge so as to beconveniently attached by rivets 7 to the upwardly projecting leg 8 ofthe side sill. The main portion of the inner side sheet 4 is disposed ina substantially vertical plane and lies immediately adjacent the bottomflange 9 of the center sill 1. At its upper edge the side sheet projectsinwardly toward the web 10 of the center sill and terminates in anupwardly projecting llange 11 secured to the latter by'rivets 12. Thelower'edges of the inner and outer side sheets of the hopper are flangedinwardly as at 13 to underlie the iloor sheet 6 and are preferablysecured thereto by any suitable means (not shown).

Secured to the outer edges of each of the hopper sheets is a door frame14 which is preferably formed as an integral unit of cast steel. Thedoor frame is trapezoidal inl A shape and is provided with asubstantially rectangular opening 15 to permit the discharge of ladingfrom the hopper. Projecting inwardly from its side and bottom edges theframe is provided with a plurality of flanges 16, 17 and 18 adapted tobe respectively secured by rivets 19 to the inner and outer side sheetsand the floor sheets of the hopper. Bordering the door opening the frameis formed with outwardly projecting sealing flanges 20 positioned so asto be in close proximity to corresponding inwardly projecting marginalflanges 21 formed on the door 22 which closes the opening. Above thedoor opening the fr ame is so formed that it may be readily secured byrivets 23 to a transversely extending inclined sheet 24 which projectsupwardly from the frame and is secured at its opposite end to a cardiaphragm (not shown). The door 22 is hingedly connected to the frame bystraps 25 which cooperate with pins 26 carried by outwardly projectinghinge lugs 27 disposed above the door opening. Any suitable mechanismmay l 'be employed for supporting the doorv in closed position such as ahook 28 which may be pivotally mounted upon the flange 17 of the framefor cooperating with an arm 29 rigidly secured to a door spreader 30mounted upon the outer face of the door.

- Alongv its lower edgethe frame is preferably rigidi-fled by adownwardly projecting liiange 31 which extends for a slight distancealong the respective side flanges 16 and 17 thereof. The sidev of theframe adjacent the center sil1` may be also advantageously reinforced bya laterally projecting rib or flange 32.

In order to produce a hopper having maximum capacity the,` inner sidesheet 4 lthereof is a-rranged as close to the center sill constructionof the car as conditions will permit. In

hopper constructions employing cast door frames it has heretofore'beenthe practice either to space the linner'side sheet from the sillasubstantial distance to permit the frame to be attached to the sheet orelse to construct the inner side of the frame so that it conformsgenerally to the contour of the adjacent center sill.

a plurality of flanges respectively secured tov the hopper sheets, theflange of the frame secured to the inner side sheet being interposedbetween it and the car center sill yand being disposed in a. planeforming an angle with the general plane of the said inner sheet.

4. A door frame for railway hopper cars having a plurality of flangesadapted to be respectively secured to the inner and outer side sheetsand the inclined iioorsheet of a hopper, the ange of the frame adaptedlto be secured to the inner side sheet of the hopperlb'eing bentoutwardly and disposed in a plane forming an oblique angle with thegeneral plane of the said side sheet. f

5. A door frame for railway hopper cars having a plurality of flangesadapted to be respectively secured to-the inner and outer side sheetsand the inclined 'floor sheet of a hopper, -said frame being alsoprovided with a plurality of door sealing flanges, the flange of theframe adapted to be secured to the in,- ner side sheet of the hopperandthe adjacent sealing flange being respectively disposed insubstantially vertical angularly disposed planes.

In testimony whereof I aiiix my signature.

inwardly bent portion 33 of the inner sheet, y I* I being secured to thelatter by the rivets 19. The flange 16 is preferably secured to th'eouter face of the innerside sheet,.being interposed between it and theadjacentcenter sill.

The foregoing construction results in the production of a hopper which,having regard for the limitations in dimensions imposed thereon by thecar construction, has extremely l large capacity. i

I claim: f 1. In a. railway car, the combination with a hopper involvinginner and outer side sheets and an inclined floor sheet, the outermarginal l edge of the inner side sheet being bent inwardly, a doorframe having a plurality of flanges respectively secured to the hoppersheets, the flange of the framel cooperating with the inner side sheetbeing secured to the inwardly bent portion thereof, and a door forclosingthe lading discharge opening del fined by the frame. y y

2. In a railway car, the combination with a hopper involving inner andouter side sheets and an'inclined floor sheet. a door frame secured tothe outer edges of each of sid sheets, the portions of the frame and theinner side sheet which are secured together extending at an angle to thegeneral plane of the said inner sheet, and a door for closing theladingdischarge opening deined by the frame.
